the forum question:
http://uk.mathworks.com/matlabcentral/answers/287017-imrotate-won-t-work-in-this-scenario-any-other-suggestions
asks for function other than imrotate to rotate image around any point.
The experts already commented to use padarray, but depending on where the arbitrary point is located
padarray requires different options.

imrotate rotates image around centre point, and inflates image depending on the rotation angle.

The resulting image is zoomed back 67% byt the figure display. May want to zoom back before
possible cropping.

Rotation point introduced with mouse click on image.

Furthest pixel rotation radius calculated.

Open to suggestions, feedback to improve initial version.
